gobject-introspection @1.60.2_4 : g-ir-scanner producing executable with linking problems

[serge-cohen (Serge Cohen)]

I am currently working to compile a project using gobject introspection (ufo : ​https://github.com/ufo-kit/ufo-core.git).

This package uses gobject introspection for its python interface. In the build process g-ir-scanner is runned on the source to extract API information but fails with message :

[ 74%] Generating Ufo-1.0.gir
dyld: Symbol not found: _iconv
  Referenced from: /usr/lib/libarchive.2.dylib
  Expected in: /opt/local/lib/libiconv.2.dylib

make[2]: *** [ufo/Ufo-1.0.gir] Error 1
make[1]: *** [ufo/CMakeFiles/gir.dir/all] Error 2
make: *** [all] Error 2

As I am not an expert in GIR, my understanding is likely (partly) wrong :

gi-r-scanner is producing an executable that is self-introspecting for generating the API file (in GIR format). But this executable is linked to the wrong version either of libarchive or libiconv. My guess is that both these should be taken from the MacPorts /opt/local/lib (rather than libarchive from the system and libiconv from MacPorts)

This is running MacOS 10.15.7 (Catalina) on a MBP 16p

[kencu (Ken)]

g-ir-scanner monkeys around with DYLD_LIBRARY_PATH and similar library linking guts, often with ill effects.

libiconv has been set up to flag these errors by having purposefully different symbols for system vs user installed versions of libiconv, so this library often shows the issue (as it is supposed to) but it is not the source of the problem.

In this case, /usr/lib/libarchive.2.dylib is thinking it is linked against /usr/lib/liconv.2.dylib, and so therefore uses the _iconv symbol, but it is being redirected to /opt/local/lib/libiconv.2.dylib that does not have that symbol.

% nm /usr/lib/libiconv.2.dylib | grep iconv

g-ir-scanner is a huge PITA for this reason, and we've been trying for months to get it right, without full success.

[serge-cohen (Serge Cohen)]

Thank you for such a rapid answer, and sorry to see that indeed the problem is much larger than the «small one» I have with this package.

I understand, that the cause of my problem is rather «in the upstream» because of the way g-ir-scanner is mangling the environment in which it executes its necessary processes.

Is there anything I can do here to help ? Do you feel it would help you in anyway if I'd filled a bug report to GIR ?

Also, I had much troubles to find documentation on the way g-ir-scanner is processing its input. Do you have any pointers ? Maybe understanding how to «capture» the generated executable (which is currently in a temporary directory that I never managed to catch before it is destructed) would help finding a way around…

Again, thanks for the help, and in general with the work done by MacPorts !

Serge.

[kencu (Ken)]

Well -- MacPorts has changed g-ir-scanner's code, so they won't be too happy about our bug report :>

Your best bet would probably be to dump as much info in this ticket as you can about how you're exactly trying to make this work, and see if we can get it working for you.

[michaelld (Michael Dickens)]

I'm in agreement with @kencu here: Please post whatever info you can and we'll see if we can get the g-ir-scanner working. It looks like you need to set a compile variable to get the correct iconv symbols ... thinking there's an input argument/variable to tell g-ir-scanner what you want it to do here, but I can't recall specifics off the top of my head.

[michaelld (Michael Dickens)]

Something that would be useful: actual commands you're using to download and build the project's code that uses GO-I / g-ir-scanner ...

[jmroot (Joshua Root)]

Replying to kencu:

Well -- MacPorts has changed g-ir-scanner's code, so they won't be too happy about our bug report :>

True, but the original issues that required us to change the code could be reported. Last I heard, the response was likely to be "We don't use macOS. Patches welcome," though.

[ryandesign (Ryan Carsten Schmidt)]

We did already report the problem upstream and they did not respond. Our main bug for the issue was #58574 and the upstream bug is ​https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/335.

g-ir-scanner must use DYLD_LIBRARY_PATH in order to find and use just-built libraries, but it erroneously adds system directories to that variable as well (anything the build used as -L flags) which is what causes the issue you experienced.

They "fixed" it by switching to using DYLD_FALLBACK_LIBRARY_PATH, but that is the wrong fix and must be reverted.

We have reverted that change in MacPorts and made additional changes that are supposed to ensure that system directories don't end up in DYLD_LIBRARY_PATH while local build directories do.

We have already had several cases where we thought we had it fixed and then a new situation was discovered that we hadn't considered. You may have found another such situation so we need more details about your build. Attach a build log if you can.

[mascguy (Christopher Nielsen)]

Let us know if this is still an issue, after updating to the latest version (1.70.0).

[ryandesign (Ryan Carsten Schmidt)]

comment:ticket:65905:2 says it's still a problem.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #71209.

[dkossack]

I am at:

MacPorts base version 2.10.4

root# which g-ir-scanner
/opt/local/bin/g-ir-scanner

root# g-ir-scanner --version
g-ir-scanner 1.78.1

Build of Gexiv2 continues to fail...

Is this ticket/issue being actively pursued? Is there something here that I am missing, that will fix the issue?

This is a long shot, but... can you provide the output of otool -L /opt/local/lib/libexiv2.dylib?

Another idea, can you run sudo port clean gexiv2 followed by sudo port -t install gexiv2? (I doubt this will help, but just throwing out ideas.) Assuming it fails, attach the main.log.

Which doesn't make any sense, as that almost suggests that Meson isn't installed. But it is based on the earlier entries in the log.

A related warning is this:

Assuming you installed MacPorts from scratch, via your custom prefix (/Volumes/PEluard/opt/local), all MacPorts-related paths should be prefixed with that. But the fact that /opt/local also exists, suggests something more is going on.

Is /opt/local a symlink to /Volumes/PEluard/opt/local? Or do you have another MacPorts setup installed in /opt/local?

EDIT: Or is /Volumes/PEluard your boot volume?

From your latest main.log, the following failure occurs:

configure sh: /Volumes/PEluard/opt/local/bin/meson: No such file or directory

Which doesn't make any sense, as that almost suggests that Meson isn't installed. But it is based on the earlier entries in the log.

Is /opt/local a symlink to /Volumes/PEluard/opt/local? Or do you have another MacPorts setup installed in /opt/local?

Yes, it is a samlink:

sh: /Volumes/PEluard/opt/local/bin/meson: No such file or directory

Warning: The following existing files were hidden from the build system by trace mode:
  /opt/local/bin/meson-3.12
  /private/var/select/sh
Warning: The following file inside the MacPorts prefix not installed by a port was accessed:
  /Volumes/PEluard/opt/local/bin/meson

Ok, /Volumes/PEluard/opt/local/bin/meson is not visible to the port because MacPorts doesn't think it was installed by a port and because you have enabled trace mode (-t).

Users were never intended to replace /opt/local by a symlink. You may have discovered another of the surprising ways in which this can fail. I haven't looked into it but off the top of my head I'm not sure why this is happening or how it might be corrected, short of either not using trace mode or removing the symlink and moving /Volumes/PEluard/opt/local back to /opt/local.

The trace mode was at the request of mascguy (Christopher Nielsen) earlier in the thread... The symlink has been working ok, in the past there were some breaks but I have straightened out most of the issues at this point. I don't think this is the problem. @mascguy (Christopher Nielsen): GIMP2 was working before, I didn't even know that gexiv2 existed. What really changed between gexiv2 0.14.2 and gexiv2 0.14.3 ?? I looked for a copy of gexiv2 0.14.2 to reinstall so I can get GIMP2.10.38 working again but I didn't come up with anything. Am I the only one having this issue??

Replying to dkossack:

Is there something here that I am missing, that will fix the issue?

If a fix were known, it would be in the port and the ticket would be closed.

Ok, well, evidently trace mode doesn't work when the MacPorts prefix has been replaced with a symlink, at least not with this port, so let's stop trying to use trace mode now.

What really changed between gexiv2 0.14.2 and gexiv2 0.14.3 ??

Per [9cac4f2540a9aa366fdc2142973c58b2600da110/macports-ports], nothing changed with the port other than the version update.

The changes listed for 0.14.3 in ​gexiv2's NEWS file don't sound relevant to this issue.

I looked for a copy of gexiv2 0.14.2 to reinstall so I can get GIMP2.10.38 working again but I didn't come up with anything.

You can try wiki:howto/InstallingOlderPort however it's by no means certain that the gexiv2 0.14.3 update is what causes the problem to happen; it could instead be an update to one of its dependencies, for example. Or it could be, as Chris suggested, interference from other installed ports that are not dependencies which, using trace mode, if it worked, would rule out.

Am I the only one having this issue??

At least the person who reported this ticket four years ago experienced the issue, and the other people who filed duplicate bug reports since then, and per earlier comments there were several other similar tickets that we thought we had fixed but evidently haven't.

No gobject-introspection developer has ever responded to ​the bug report I filed four years ago so they obviously don't care that their software doesn't work.
